RAMlVlER FOR BREECH-LOADING GUNS.

SPECIFICATION forming part of Letters Patent No. 625,240, dated May 16,1899.

Application filed February 23, 1899. Serial No. 706,522. (No model.)

To {ZZZ whom t may concern:

Be it known that I, WILLIAM H. BEvANs, a citizen ofthe United States,residing at Vashingtonjn the District of Columbia, have invented new anduseful Improvements in Rammers for Breech-Loading Guns, of which thefollowing is a specication.

My invention relates to a ramnier for breeclr loading guns soconstructed that when not in use it occupies comparatively small spacebehind the gun, but for ramming it is rapidly elongated, so as to forcethe charge into the breech of the gun. For this purpose I construct therammer as I shall describe, referring to the accompanying drawings.

Figure l is a longitudinal section of the rammer extended. Figs. 2 and 3are longitudinal sec-tions, to an enlarged scale, of the rear part andfront part, respectively, of the rammer iuits contracted condition. Fig.4 is a transverse section on the line 4. 4. of Fig. 3, the chains, rope,and their xings being omitted.

a is a cylindrical casin g, which is supported and fixed in anyconvenient position behind the gun, with its axis in line with that ofthe gun-bore. To the tube a are attached two side frames ZJ b, havingbearings for the axes of a winch, having a barrel c for a wire rope anda chain-barrel CZ. These axes are geared together, so that the barrel cmakes four revolutions for each revolution of CZ'. On the front end ofthe casing a is mounted a pulley @around which passes a chain f, havingits one end fixed to the barrel CZ and its other end fixed to the rearend of a tube g. On the front end of g is mounted a pulley h, aroundwhich passes a chain fi, having its one end iixed to the front end ofthe tube g, while its other end is iiXed to the rear end of a tube 7'. Asimilar arrangement of pulleys 7.5 and Z and chai-ns 'm and u isrepeated for two other tubes o and p, and on p is fixed the rammer-headr.

At the front ends of the casing a and of the several tubes g, j, and oare fitted annular bushes q, and in the annular spaces between thecasing and the several tubes, which are all concentric, are fittedlinings s, so that all the tubes can slide telescopically. The

tubes are slotted along their lower sides to 5o accommodate the chains.To the rear end of the innermost tube p is fixed one end of a wire ropet, which passes around a pulley u, mounted on the rear end of the casinga, and has its other end attached to the barrel c. Vhen the rammer hasto be elongated, the barrel cis turned in the direction of the a1'- rowby a crank-handle w, the barrel d being turned at one-fourth of thespeed in the opposite direction. As the chain fis Wound on 6o the barrelCZ it causes the tube g to advance, thus drawing the chain t, causingthe tube j to advance,'and so on, the rammer-head r being thus movedforward. For retracting the rammer the barrel c is turned inthe oppositedirection, winding on it the rope t, and thereby drawing back the tube1o and head r and the other tubes successively, the head lr meeting theend of the tube o, shoulders @c on the tubes o, j, and g meeting bushesq of 7o the tubes j and g and a, respectively.

-Obviously instead of four sliding tubes, as shown in the drawings,there might b e a less or greater number, the gearing of c to CZ beingvaried accordingly.

Having thus described the nature of this invention and the best means Iknow of carrying the same into practical effect, I claim- A rammer forbreech-loading guns comprising atubular casing several concentric tele-8o scopically-sliding tubes fitted with bushes and linings the innermosttube carrying a rammer-head, mounted on the casing a winch and achain-barrel suitably geared together, guide-pulleys on the casing andon the tubes except the innermost chains connecting the barrel to theoutermost tube and the tubes .to one another also a wire rope connectingthe winch to the innermost tube substantially as and for the purpose setforth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

WILLIAM H. BEVANS.
